EMERY-WHEEL DRESSER.

Application filed July 21,, 1910. Serial No. 573,093.

To all whom it may concern .7

- Be it known that 1, PAUL WARD LAMsoN, a citizen of the United Statesof America, residing at No. 2835 Virginia avenue, city of Louisville, inthe county of deiferson and State of Kentucky, have invented certain newand useful Improvements in Emery- N heel Dressers, of which thefollowing is a specification, reference being had therein to theaccompanying drawing.

This invention relates to rollers for dressing emery and other abradingwheels, and the principal object of the same is to provide a dressingroller that is composed of a plurality of disks having an interlockingengagement that prevents relative rotation,

' and in which the peripheries of the disks are shaped so that angularscraping edges are provided.

In carrying out the objects of the invention generally stated above itwill be understood, of course, that the essential features thereof arenecessarily susceptible of changes in details and structuralarrangements, one preferred and practical embodiment of which is shownin the accompanying drawings, wherein I Figure l is a view in sideelevation of the improved dressing roller. Fig, 2 is a front viewthereof. Fig. 3 is a view in, side elevation of the center disk of theroller. Fig.

4 is a central transverse sectional view of the roller. Fig. 5 is a@detail perspective 316;; of one of the outer disks and the centerReferring to said accompanying drawings by numerals, itv will be seenthat the improved dressing roller is composed of the outer disks 1 and 2and the inner or central disk 3, The central disk 3 is provided with .ahub 4 the ends of which have the alternating, lugs 5 and recesses 6formed thereon. The outer disks 1 and 2 are duplicates, and their hubs 7have their inner, ends provided with alternatingvlugs 8 and recesses 9complemental to the lugs and recesses of the hub 1 of disk 3. The outerends of hubs 7 are provided with a circular rib 10.

The disks 1, 2 and 3 are provided with radial corrugations and when thesame are assembled in interlocking engagement, said corrugations providethe periphery of the roller with two annular rows of diamond shapedrecesses 11 which are arranged in staggered relation so that the edgesthereof present various angles to the emery or other stone to bedressed.

In assembling the disks, the lugs and re-' cesses of the hub of thecenter disk 3 are placed into interlocking engagement with the lugs andrecesses of the hubs of the disks 1 and 2, and a sleeve 12 preferably ofhard metal, is passed through the hubs and the ends 13 of said sleevecrimped over the end ribs 10 of the hubs of. said disks 1 and 2, .so

that relative lateral movement of the disks 1, 2 and 3 is prevented. Abushing 14, prefrecesses, the continuous angular edges of which willefiecti'vely dress the surfaces of emery or other wheels. And that thedisks being in flush-contact between the corrugations prevent peripheralgrooves being formed on the roller, such as would tend to produce ribsor other raised portions on the work being treated.

What I claim as m invention is In an emery wheel resser, a series ofcutter wheels each having a hub and a cutter blade extending from thehub, a sleeve on which said wheels are mounted, and means to hold saidwheels locked'together, said means comprising a series of interlockinglugs and pockets formed on adjacent wheels, and a sleeve passingthroughthe hub and having its ends beaded directly on the outer surfacesof the outside cutter wheels.

In testimony whereof I hereunto aflix my signature in presence of twowitnesses. PAUL WARD LAMSON.
